Binoculars with magnification 25x and objective diameter 70 mm.
It features large aperture and high-quality optics providing a sharp image all the way to the edge. It is mainly designed for astronomical observation, as well as being easily suitable for nature or planes in flight. It is covered with a layer of rubber, which makes it more secure in the hand.
Faithful colors and bright images are due to prisms made of high-quality glass BaK4. Multilayer coatings (Multi Coated) reduce light loss. The binoculars use a "porro" prism system. Binoculars having this type of system are larger in size, while they often offer a wider field of view.
.
Due to the high magnification, it is worth considering the use of a tripod when making observations - a tripod adapter is included. In addition, caps, a small lens cloth, a strap, and a carrying case are also included.
